Quick answer
The Circuit Blox 800 set lets you build 800 different projects including light shows, sound effects, spinning motors, and a unique electromagnetic inductive windmill that runs continuously.
What makes the 800-set different from smaller Circuit Blox kits
With 800 projects, this set is the largest standalone Circuit Blox kit available. It includes a wider variety of electronic components than smaller sets like the 120 or 395, which means you can build more complex circuits and experiment with multiple outputs at once.
The inclusion of an electromagnetic inductive windmill is a standout feature not found in smaller kits. It demonstrates wireless power transfer in a tangible way, making it a great conversation starter for curious kids.
Who should consider this set
This kit is designed for kids aged 8 and up, but it also appeals to older beginners and hobbyists who want a structured introduction to circuitry. The 800 projects provide a clear progression from simple light circuits to more advanced builds involving motors and electromagnetism.
If you're a parent looking for a STEM toy that offers long-term engagement, the sheer number of projects means your child won't run out of things to build quickly. It's also suitable for classroom use where multiple students can rotate through different builds.
What you cannot build with this set
While 800 projects is extensive, the set does not include programmable microcontrollers, sensors, or Bluetooth modules. If you're looking for coding or IoT projects, you'll need a different platform like Arduino or a more advanced robotics kit.
The set also lacks a storage case, so you'll need to provide your own container for the blocks. This is a minor inconvenience but worth noting if organization is a priority.
Decision rules for buying the Circuit Blox 800 set
- Project variety: Choose this set if you want a wide range of projects from simple lights to complex motor and electromagnetic builds. The 800 projects cover multiple difficulty levels.
- Age and skill level: Ideal for ages 8 and up. Younger children may need adult help with some builds. Beginners will find plenty of easy projects to start with. Check the recommended age and be prepared to assist if needed.
- Educational value: The set teaches basic circuit principles, electromagnetism, and motor mechanics without requiring a screen. It's a pure hands-on STEM experience.
- Storage and organization: No storage case is included. Plan to use a small bin or bag to keep the blocks together between builds. Consider buying a storage solution separately to avoid losing small parts.
